Huawei claims 100Mbps possible over 800m copper lines

SuperVector ekes out more performance.

Chinese networking vendor Huawei claims to have built a SuperVector prototype that provides up to three times the bandwidth over copper lines of standard VDSL2 vectoring.

Vectoring utilises noise-cancelling technology to reduce interference that would otherwise harm data signal transmission. The technology greatly improves performance over shorter copper runs where the entire cable sheath is managed by one device to control the interference between the line pairs.

Huawei's SuperVector technology bumps up the bandwidth range from 17MHz to 35MHz, adds a new encoding method and other optimisations that together boosted the performance of broadband over copper to 100Mbps over 800 metres in lab tests, the company said.

On shorter 300 metre runs, Huawei claimed SuperVectoring achieved 400Mbps.

The fast speeds make SuperVectoring suitable for delivering high-definition 4K video over DSL, according to the company.

Whether or not the Huawei techology will appear in Australia's mixed-mode NBN broadband network - thanks to the recently signed China-Australian Free Trade Agreement (CHAFTA) - remains to be seen.

The vendor was banned from bidding on the NBN due to the then-Labor Government's fears over cyber attacks originating out of China.

Across the Tasman however, Huawei has scored several large contracts as part of New Zealand's ultra-fast broadband (UFB) fibre to the premises network build.

Huawei also built the third GSM network for 2 Degrees in New Zealand and also beat out incumbent Spark's long-time equipment and deployment partner Alcatel-Lucent for a nationwide 4G LTE upgrade.
